"You can also go back through alone on a harder difficulty and try to get more achievement points. The missions are well-designed and varied enough that this is much realer possibility than in other shooters.
While this game may have its online issues, nearly everything else about it is flawless. If you are a shooter fan, you must play this game. The controls, graphics, and immersive experience are all nearly pitch-perfect. Offline, the game is always a fun experience, and all the modes are worthy of replay. I would recommend clearing out some play time for this game this year."
